Chapter Nine - Hypothesis Testing and
Effect Size: Two-Sample Designs
Chapter
Objectives
- Describe the logic of a simple experiment
- Explain the testing of a mull hypothesis when there are two
samples
- Explain some of the reasoning in finding degrees of
freedom
- Distinguish between independent-samples designs and
correlated-samples designs
- Calculate t- test values for both independent-samples
designs and correlated-samples designs and write
interpretations
- List and explain the assumptions for using the t
distribution
- Calculate and interpret an effect size index
- Describe the factors that affect the rejection of the null
hypothesis
- Distinguish between statistically significant results and
important results
